摘要： A camera includes a lens barrel which can be retracted into a camera body, and a lens barrel storage control apparatus. The lens barrel has a front lens group mounted in a front end portion thereof and a rear lens group movably disposed therein. The lens barrel storage control apparatus controls a DC motor for retracting the lens barrel, if the rear lens group is in a safe area where it will come into no contact with a film in retracting the lens barrel into the camera body, and then controls a stepping motor for locating the rear lens group to a final standby position after completion of storage. On the other hand, if the rear lens group is out of the safe area, the control apparatus controls the stepping motor for locating the rear lens group to the rearmost position in the safe area, and controls the DC motor for retracting the lens barrel.

摘要： A camera includes a lens barrel which can be retracted into a camera body, and a lens barrel storage control apparatus. The lens barrel has a front lens group mounted in a front end portion thereof and a rear lens group movably disposed therein. The lens barrel storage control apparatus, first, controls a stepping motor for driving the rear lens group to locate the rear lens group at a standby position in the barrel, and then controls a DC motor for driving the lens barrel to retract the lens barrel into the camera body while keeping the rear lens group at the standby position. Also, when it is detected that the rear lens group is not located at the standby position, the control apparatus controls the DC motor to locate the lens barrel at a suitable position within a range where the lens barrel can be set in a photographable state.

摘要： A camara control device continues a pre-winding or a first frame setting when a pre-winding or a first frame setting is stopped in the middle because a battery of the camera is taken out or because of exhaustion of the battery and after that another battery is loaded. The camera control device writes a pre-wind signal to an electrically rewritable non-volatile memory E.sup.2 PROM when a pre-winding is started and erases the pre-wind signal in the E.sup.2 PROM when the pre-winding is finished, and writes a first frame set signal to the E.sup.2 PROM when a first frame setting is started and erases the first frame set signal in the E.sup.2 PROM when the first frame setting is finished. If the pre-winding or the first frame setting is stopped in the middle, the pre-wind signal or the first frame set signal in the E.sup.2 PROM is not erased. The camera control device, responsive to loading of the battery to the camera, continues the pre-winding or the first frame setting when the pre-wind signal or the first frame set signal is left in the E.sup.2 PROM.

摘要： A drum cleaning apparatus for an electrophotographic copying machine includes a toner image forming drum rotatable about a horizontal axis, a blade for scraping off toner particles deposited on the cylindrical outer surface of the drum, an inclined toner particle guide plate having an upper edge bearing on the outer surface of the drum upstream of the scraping blade as viewed in the rotating direction of the drum and a lower edge positioned at an opening of a toner collecting container, a holding structure for supporting the toner guide plate and mounted swingably on a shaft with play, the shaft extending in parallel with the axis of said drum. Feeble and periodical shocks are applied to the toner guide plate by way of the supporting shaft thereby to promote the sliding down of the toner particles on and along the guide plate into the collecting container to prevent accumulation of the particles on the plate.

摘要： An exposure compensation device of a camera used jointly with an electronic flash has a plurality of exposure compensation modes and electronic flash modes preset to each of the exposure compensation modes. In each exposure compensation mode, a compensation value for compensating an exposure value and an electronic flashing point is set. When an exposure compensation mode is requested by an external operation, the exposure compensation device selects a required exposure compensation mode based on results of light measurement and distance measurement, compensates an exposure value and an electronic flashing point corresponding to the results of light measurement and distance measurement by means of the compensation value of the selected exposure compensation mode, and sets an electronic flash mode corresponding to the selected exposure compensation mode. Therefore, an operation of exposure compensation using an electronic flash is made easier, and, the contents of exposure compensation using an electronic flash is changed automatically.

摘要： For removing toner from a photosensitive drum roll for electrophotography, a blade contacts the surface of the drum roll at a location where said surface is moving upwardly, to scrape residual toner therefrom. A resilient transfer roll, spaced below the blade, carries away toner that falls from the drum roll. The transfer roll is directly rotatably driven by the drum roll. One of the rolls has enlarged diameter end portions for driving contact between the rolls at zones outside the image area of the drum roll. The resilient transfer roll is urged toward the drum roll under a biasing force that radially compresses its end portions to maintain it either in merely line contact with the image area of the drum roll or spaced from that area by a distance less than the diameter of toner particles.
